Pretty much the only thing I haven't purchased yet for my new system is a Case/PSU. When I go to buy the PSU, what kind of power do I need for the following?
- P4 2.8GHz
- GigaByte 8KNXP
- 2x256MB Corsair TwinXLL
- ATI Radeon 9800 Pro 128MB
- Western Dig. 80GB SE (WD800JB)
- Lite-On CD-RW
- Lite-On DVD-ROM
- SB Audigy 2
I probably will not overclock anything, and I probably won't add/upgrade too much for a good while...maybe a SATA hard drive when they get a little cheaper and/or I fill up 80GB.
How much PSU do I need?

180w should be enough, anything bigger will be overkill
Seriously now. Your system probably won't draw more than 180w, so go with a 300w PSU and you will have plenty of headroom for upgrading, and even overclocking if you change your mind. Choose a quality PSU from the recommended section, and it will be fine.

German magazine C't tested 875 and 865 motherboards. They all draw 70% of the whole current on the 12V line. You PC will probably need more than 200W AC: http://www.computerbase.de/article.php?id=227&page=4
Let's take safe 220W:
220W * 70% PSU efficiency * 70% = 110W. You will need a PSU with at least 10A on the 12V line.
